The Renusol Wood Screw for Slate (Part No: R900013) is a countersunk wood screw designed specifically for use with Renusol's slate roof hooks. Sized at 6mm diameter x 80mm length, it is used to fix the stainless steel slate roof hook through a slate and into the rafter beneath, forming the structural fixing point for a pitched roof solar mounting installation on natural or manmade slate.
This screw differs from Renusol's standard pan-head wood screws (used on flat/plain tile roof hooks) in that it uses a countersunk head, allowing it to sit flush where the slate roof hook design requires it. Two of these screws are supplied as standard with the Renusol slate roof hook set (Part No: R920005).

Screws Per Slate Hook Set
Good to Know: Two R900013 screws are supplied as standard with the Renusol slate roof hook set (Part No: R920005). This listing covers the screw specification for cases where replacements or extra fixings are needed.
Countersunk Head Design
Unlike Renusol's pan-head screws used on flat/plain tile roof hooks, this screw uses a countersunk head to sit flush with the slate roof hook's mounting design.
Purpose-Built for Slate Roof Hooks
Specifically sized and specified for fixing the Renusol stainless steel slate roof hook through a slate and into the rafter beneath.
6mm x 80mm Sizing
The 6mm diameter and 80mm length give secure thread engagement into typical UK rafter timber, matching the structural demands of a slate roof fixing.
Supports Weathertight Slate Refitting
The bracket is fixed through one slate to the rafter beneath, and the slate above is replaced over the fixing so the roof remains weathertight.
Recommended Lead Soaker Where Near Slate Edges
Where the bracket sits close to the edge of the covering slate, a lead soaker over the bracket is recommended to maintain a fully watertight roof.
Consistent System Integrity
Using the correct Renusol-specified screw helps preserve the structural rating and weatherproofing the slate roof hook system was designed around.
Important Safety Information: Renusol mounting equipment must not be used with mounting equipment from other suppliers. Substituting a non-Renusol screw could compromise both structural performance and the mounting system's warranty.

What is this screw used for?
This countersunk screw is used to fix a Renusol slate roof hook through a slate and into the rafter beneath, forming the structural fixing point for a slate roof solar installation.
How is this different from Renusol's other wood screws?
This screw uses a countersunk head, whereas Renusol's screws for flat/plain tile roof hooks (such as REN-900318) use a pan head. The countersunk design suits the slate roof hook's mounting requirements.
How many of these screws come with a slate roof hook?
Renusol's slate roof hook set (Part No: R920005) includes 2 of these screws as standard.
Do I need any additional weatherproofing when using this screw?
Where the bracket sits close to the edge of the covering slate, a lead soaker over the bracket is recommended to keep the roof fully watertight.
Can I use a different manufacturer's screw with my Renusol slate hook?
No. Renusol mounting equipment must not be used with mounting equipment from other suppliers, as this can affect structural performance and the mounting system's warranty.
